Skip the PP 30s?

[citanul]

In the past couple of weeks, I've seen a few mentions of the idea that while moving up the SNG ladder, the 30s could/should be skipped. I'm beating the 20s pretty well at the moment, but a rough patch at the 30s right when I moved up has me stepping back for a moment. My bankroll is fat for the 30s, but clearly nothing is large enough if you're not beating the game.

My ROI at the 10s is about 45%, my ROI at the 20s is about 43%, and through a smallish sample size, my ROI in the 30s is somewhere around, er, 1% or so?

I've seen a few arguments for why to skip the 30s, mostly that it's sort of a different group of players in the 10s-30s than the 50s-up, and that the 30s are by far the hardest of the lower levels.

Any advice?
